Brothers Harris and Sable provide spark and foundation for physicist's work

Brother Harris provided the spark and Brother Sable provided the foundation for Tony Mezzacappa's early interest in physics. "I credit my getting involved in physics to a high school physics teacher, Brother Harris of Monsignor Farrell High School on Staten Island," says Dr. Mezzacappa, Corporate Fellow and Group Leader for Theoretical Astrophysics in the Physics Division of the Oak Ridge National Laboratory.
